Sit-to-walk (STW) and sit-to-stand-and-walk (STSW) are rise to walk transitions.
Healthy subjects require less vertical force to rise from a higher seat height.
Neither seat-height or lead-limb affect STW or STSW dynamics in healthy subjects.
Normative data independent of lead-limb may inform rise to walk rehabilitation.
Gait initiation (GI) in STSW is distinctive from GI following quiet-standing.
